以直驱式永磁同步风力发电机为研究对象，在Matlab/simulink平台建立了风力机模型、传动系统模型，采用变桨距控制。(Taking the direct drive permanent magnet synchronous wind turbine as the research object, the wind turbine model and the transmission system model are established on the MATLAB / Simulink platform, and the variable pitch control is adopted.)
